  • 摘要: 利用60Coγ射线、电子束辐照刚果红水溶液,研究其降解行为.考察了刚果红水溶液辐照前后紫外可见光谱的变化、刚果红的降解率及溶液总有机碳(TOC)的去除率.通过不同气氛饱和辐照,对比了各种活性粒子对降解效果的影响.初步研究了初始pH值、H2O2和TiO2的加入对刚果红水溶液降解效果的影响.结果表明,60Coγ射线、电子束辐照是一种有效的去除水体中刚果红染料的方法,其降解效果在不同体系中均可以达到100%.高剂量下TOC去除率可以达到85.7%.H2O2和TiO2的加入可以有效提高刚果红的降解效率.
    Abstract: 60Co γ-rays and electron beam irradiation induced degradation of an azo dye Congo Red were presented in this paper. Changes of absorption spectra,degradation and TOC removal were investigated. The effect of reactivity of different water radiolysis intermediates(eaq-,·OH,·O2-/HO2·)was discussed. Different initial pH value of the solution and the addition of H2O2 and TiO2 gave birth to some distinction phenomenon during the degradation of Congo Red. The complete degradation of the dye was observed at the absorbed doses in different irradiation systems. The removal of TOC can reach 85.7% when the solutions were saturated by O2and N2O. The results show both 60Co γ-rays and electron beam irradiations are effective techniques in the removal of dyes in water. TiO2 is a potential catalyst in irradiation induced degradation of Congo Red.
